Does the Rear Diffuser for S550 fit a GT350 or Mach 1 with the factory differential cooler?

Yes, with the Verus install kit. The Rear Diffuser for S550 bolts directly to the regular Mustang, but the GT350, GT350R and Mach 1 carry a factory differential cooler, and Verus Engineering sells a separate install kit to clear it. The kit is not included, so order both for those models.

Will the Verus Mustang diffuser fit my aftermarket exhaust?

Yes, if Verus Engineering has confirmed it. The factory exhaust and Corsa Extreme and Sport fit as delivered, while Borla Touring, the Borla Ford Performance option, Gibson and Roush systems need a reversed bracket, bracket changes or spacers. Ask before ordering for any other system.

Does the diffuser fit the Shelby GT500?

Yes, with minimal modification, according to Verus Engineering. The diffuser is a direct bolt-on for the regular S550 chassis, and Verus states it also fits the GT500 once minor changes are made, without detailing them, so plan the install with a shop that knows the GT500.

What does a rear diffuser do on a Mustang?

It builds a low-pressure zone under the rear of the car, reducing lift and drag together. Verus Engineering reports that its diffuser improves the aerodynamic efficiency of the S550 chassis and adds tire grip at speed, with strakes that generate vortices to hold the airflow against the diffuser surface.

What material is the Verus S550 diffuser made from?

Verus Engineering starts with 5052-H32 sheet aluminum, laser cuts and press-brake forms it on CNC machines, and applies a textured black powder coat with a low sheen. The hardware is stainless, the diffuser is made in the U.S.A., and its shape follows in-house scans of the S550 for a near-OEM fit.

Description

Verus Engineering Rear Diffuser for S550 Ford Mustang

Verus Engineering’s Rear Diffuser for S550 Ford Mustang gives the back of the car a working underside, lowering lift and drag on the S550 chassis with a non-aggressive strake layout that keeps the rear view clean. It bolts straight on to the regular Mustang, and Verus lists the stock exhaust plus a range of Borla, Corsa, Gibson and Roush systems as compatible. It suits the owner who wants measurable function without a race-car look; GT350, GT350R and Mach 1 owners also need the separate Verus install kit that clears the factory differential cooler.

Construction

Verus cuts the panel from 5052-H32 sheet aluminum on a CNC laser, bends it on a CNC press brake and finishes it in a low-gloss textured black powder coat. Its strakes lock into the main plane with a Verus construction method and generate vortices that keep air attached to the surface. Paired with a front splitter, it gives the S550 a well-proportioned aero balance, Verus says.

About Verus Engineering

Verus Engineering designs aerodynamic and performance parts in Indianapolis, Indiana. Two engineers founded it in late 2014 as Velox Motorsports and renamed it in 2017 after a trademark dispute; verus is Latin for true or complete. Each design starts from a 3D scan of the car, is developed with CFD and finite element analysis and is validated on track, across more than 20 platforms from the GR86 to the C8 Corvette.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
